NEW ORLEANS (AP) -- Floodwater lingered in Plaquemines Parish, more than 240,000 electricity customers sweltered without power and officials north of Lake Pontchartrain kept a wary eye on waterways swollen by Hurricane Isaac.
The storm made landfall Tuesday, but residents are still suffering days later.
Much of New Orleans had electricity, but work crews continued to deal with toppled trees and downed power lines.
North of Lake Pontchartrain, a mandatory evacuation near the Bush community was dialed back to a voluntary evacuation after authorities stabilized a lock on the Pearl River Diversion Canal. But officials said the West Pearl River was in danger of flooding.
Homeland Security Secretary Janet Napolitano was set to visit storm-struck areas of south Mississippi and Louisiana on Sunday. President Barack Obama was expected in Louisiana on Monday.
